the parts are eX'ceedingly "strong, Aand'relable in action. A' principal 'feature of the-invention, gen- Y:erally stated,- consists inv `arranging lfthe "knuckle lock upon the guard/arm side of the ycoupler head and in forming the knuckley the-portion thereof which co- "ing `from the spirit ofthe invention.

Another feature ofthe invention consists in providingA the stop shoulder for cooperatin with the 'inner end of the tail of the knuckle to limit outward rotation of the In the drawings villustrating a preferred form of the invention- Figure 1 is a plan-view of av car coupler embodying the invention.

In advance of the lockd thecoupler head is providedwith an interior recess 11 which lock which,cooperates'with `the lock engag-f" extends laterally-outward beyond the lock supporting-facefor abutment 8. The recess 11 is preferably of channel form, termif nating at its forward end in a shoulder and communicating atts rearend with the lock receiving recess o'fthehead. vThe shoulder 12 -fornis a .stop which is adapted to be engaged Y i' l by the lock engaging portion 10 of 4the vknuckletail so as to limit uncoupling move` f 1 Y A ment of the knuckle,V thus ypreventing it from passing 'from beneath the lock.A Above .and

The oppositely extending flanges 13 and'14` r1`he modied form of? construction shown 'i in Fig. 5 is the same as that `heretofore de-V scribed, eXcept'that outward rotation of the knuckleV 3 is limited by the engagement of a stop shoulder l5 on the knuckle with a porhaving a head and shank, a knuckle pivotally Vmounted on said head, and a lock for the knuckle, said head being provided on its interior with a face forming an abutment for supporting the lock against the force applied thereto by the knuckle, said abutment face being spaced laterally from said shank toward ing provided in advance of said abutment y the guard arm side of the head, said head be- With a recess adaptedto receive the inner end of the knuckle tail When the knuckle is in ,open-position, and said head also being` provided on its guard arm side adjacent said recess With means or preventing the knuckle .tail from swinging outwardly so as to be Withdrawn `from beneath said lock. y

2. A car coupler having reduced size standf ard contour and involving a coupler body 'formed with a head and shank, a knuckle pivotally mounted on said head, and a lock for said knuckle, said head being provided With a face forming an abutment for re` sisting the force applied to the lock by vthe knuckle, said face-being substantially parallel to the longitudinal axis of the coupler and being spaced laterally beyond said shank toe Ward the guard arm side of the coupler head,

and the inner end of the tail of said knuckle having a lock engaging portion which projects laterally beyond said abutment ace toward the guard-arm sid-e of the coupler head when the knuckle is in open position.

'3. A car coupler having reduced size standard contour and involving a coupler body lia-ving ahead and shank, a knuckle pivotally mounted thereon, and a lock for the knuckle, saidheadbeing provided on itsv interior With a faceI forming an abutment for lsupporting the lock against force applied thereto by the knuckle, said face being spaced laterally from said shankl toward the guard arm side of the head, said head having a recesson its guard arm side for accommodating the innerkend of the ytail of the knuckle when the latter is in open position, and also beingv provided on its guard arm side with a vstop 'for limiting outward rotation of the knuckle to prevent the Ylatter from passing lWholly from beneath said knuckle.

A car coupler havingreduced size standn ard contour and involving a coupler head, a knuckle pivotally mounted thereon, and a lock for the knuckle, said head being provided on its guard arm side with a recess for" receiving the lock and also being formed on the guard'arin side with a channel in advance of said recess and communicating With the latter, said channel being closed' at its forward end and adapted to accoininodateithe inner end o the knuckle tail when the knuckle is open position.
